K&N 33-2438 Air Filter Product Reviews

I have a 2010 Lexus GX 460. (UR-FSE 4.6L V-8) I get 17 to 20 mpg with this filter. Easily +5 mpg over the paper filter. I own two of the K&N filters so I swap in a clean filter as often as I want with no waiting.

It does give a little extra kick to it, it definitely made my gas mileage go from 17 -19.3 now.

I have used K&N air filters for almost 20 years. The price of one K&N filter is equal to about three paper-factory filters. The additional plus is the money you same with the added fuel mileage. I figured it takes about 8-10 tanks of fuel to pay for most air filters. I’m not an accountant but I know the K&N saves me money. Reagan Houston, Texas
